It’s not uncommon to find yourself needing to downgrade node version on your Windows computer. Perhaps you’re experiencing compatibility issues with a certain package, or maybe you need to switch to an older version of Node.js for a specific project. Whatever the reason, downgrading your Node.js version can be a daunting task, especially if you are not familiar with the process. In this article, we will guide you through the steps to downgrade your Node.js version on Windows.
Steps to Downgrade Node Version on Windows
Step 1: Uninstall Current Node.js Version
The first step in downgrading your Node.js version is to uninstall the current version that you have installed on your machine. To do this, follow the steps below:
1. Open “Control Panel” on your computer.
2. Click on “Programs and Features.”
3. Find the current version of Node.js installed on your machine and right-click on it.
4. Click “Uninstall” and follow the prompts to complete the uninstallation process.
Step 2: Download the Older Node.js Version
Once you have uninstalled the current version of Node.js, head over to the official Node.js website and download the older version you wish to install.
Step 3: Install the Older Node.js Version
After downloading the older version, follow the installation process as you would with any other software installation on your computer. Be sure to select the correct version during the installation process.
Step 4: Update NPM
By default, the older version of Node.js you just installed may come with an older version of NPM (Node Package Manager). To ensure that you are running the latest version of NPM, run the following command in your terminal:
npm install -g npm@latest
Step 5: Test the New Node.js Version
Once you have successfully installed the older version of Node.js, it is important to test that it is working correctly. Run the following command to check the version number of Node.js:
node -v
If the version displayed is the one you just installed, then congratulations! You have successfully downgraded the Node.js version on your Windows machine.
Step 6: Update Environment Variables
If you are running any scripts or applications that reference Node.js or NPM, you may need to update your environment variables to reflect the new installation. Follow the steps below to update your environment variables:
1. Open the “Start” menu and search for “Edit the system environment variables”.
2. Click the button labeled “Environment Variables”.
3. Under “System Variables”, find the “Path” variable and click “Edit”.
4. Add the path to the folder where the new version of Node.js is installed and click “OK”.
Step 7: Delete Node.js and NPM Folders
After uninstalling the current version of Node.js, there may be residual files and folders still left on your computer. To ensure a clean installation, delete the following folders if they exist on your machine:
1. C:\Program Files\nodejs\
2. C:\Users\{USER}\AppData\Roaming\npm\
3. C:\Users\{USER}\AppData\Roaming\npm-cache\
Step 8: Use a Node.js Version Manager
If you find yourself frequently switching between Node.js versions, consider using a Node version manager like nvm-windows. A version manager makes it easier to switch between multiple Node.js installations and helps you avoid conflicts between different versions.
Step 9: Backup Your Files
Before making any major changes or updates to your computer settings, it is always important to make a backup of your important files and data. This will ensure that if anything goes wrong during the downgrade process, you will still have access to all your files.
Step 10: Follow Official Documentation
Always refer to the official Node.js documentation when downgrading your version. The official documentation provides clear instructions on how to downgrade Node.js on Windows and ensures that you follow the recommended steps.
Step 11: Avoid Package Compatibility Issues
When downgrading your Node.js version, be sure to take note of any package compatibility issues that may arise. Make sure to test your applications or scripts thoroughly to ensure that they are still functioning as intended.
Step 12: Stay Up-to-Date
It is always important to stay up-to-date with the latest version of Node.js to take full advantage of the latest features and security updates. If you need to downgrade your version for a specific project, be sure to switch back to the latest version once the project is completed.
